SAMUEL B. STINE, OF OSCEOLA MILLS, PENNSYLVANIA.

OILER FOR CAR-WHEELS.

SPECIFICATION forming part of Letters Patent'No. 624,566, dated May 9, 1899.

Application filed February 5, 1898. Serial N0. 669,200. (No model.)

To ctZZ whom, it may concern;-

Be it known thatI, SAMUEL B. STINE, a resident of Osceola Mills, in the county of Clearfield and State of Pennsylvania, have invented a new and useful Improvement in Oilers for Oar-\Vheels; and I do hereby declare the following to be a full, clear, and-exact description thereof.

My invention relates to mine-car-wheel oilers, and more particularly to what are generally known as spring-oilers. These spring-oilers as generally constructed consist of a valve held in position by a spring and a plug adapted to bear against the spring to hold the same in place, the whole being held within a suitable cage.

The object of my invention is to provide a simple form of spring-oilerin which the parts are held within the annular oil-chamber in such a manner that no separate cage is required.

My invention comprises, generally stated, a car-wheel whose hub has an annular chamber for oil surrounding the axle-shell, said chamber having curved bearing faces or grooves with which a spiral spring engages, a valve held in place by said spring, and a plug entering an opening on the rear face of I the figures.

In the drawings the letter a designates an ordinary mine-wheel having the spokes b and the central hub c. The hub c has the annular chamber d formed therein, adapted to contain a suitable quantity of oil for lubricating purposes. This chamber cl is made up of the outer wall e and the inner wall f, said inner Wall forming the axle-shell g, through which the axle h passes. This axle-shell g has the orifice 1, through which the oil from the charm her (2 may pass to the axle and-lubricate same.

On the front face of the hub c is the supply orifice 7t, through which oil is introduced to chamber (1. A ball-valvel fits into 'a seat m, formed by the curving of the walls 6 and fat a point-surroundingsaid opening, so that said ball-valve controls the admission of oil to the chamber d. This ball-valve is prefer ably formed of steel, and the more said valve is turned and moved in its seat when oil is being admitted the better it keeps its fit in said seat. Flat valves when moved lose their seat and a leakage is liable to result.

Formed in the outer wall 6 of the oil-chain b'er d is the semicircular or curved groove or bearing 11, while opposite said groove orbearing n in the inner wall f is a like curved groove or bearing 0. These two grooves 97. and 0 form together-a bearing for the spiral spring 1)", so that said spring when introduced into said bearing through the open ing 9 at the rear of the hub will be held in position therein. The opening r is threaded and is adapted to receive a threaded plug 8. This plug 3 has the square head if, by means of which said plug may be grasped and turned by the proper tool for inserting or withdrawing same. The spring p is thus held between the ball-valvel and the plug 8, and said spring thus acts to retain said valve normally in its Seat.

To introduce oil into the chamber ol, the ball-valve l is pressed back off its seat and the spring 19 contracts. As soon as suflicient oil has been introduced and the pressure on the valve has been relieved the spring again seats said valve to prevent the escape of the oil.

The bearings for the spring,plug, and valve are all formed in the hub itself and in the walls thereof, so that no separate cage is required to inclose the parts of the oiler. This simplifies'the construction in a great measure, as the bearings for the spring can be -cast integral with the hub. The bearings for the spring are suflicient to prevent the displacement of the spring when the wheel is sub jected to severe jars and jolts.

What I claim as my invention, and desire to secure by Letters Patent, is-

A car-wheel provided with ahub having an between the valve and plug and fitting in annular chamber formed therein and grooves said grooves. 10 formed on the inner and outer faces of said In testimony whereof I, the said SAMUEL B. chamber and connecting with a supply-orifice STINE, have hereunto set my hand.
